Гладкая Водонепроницаемая кровельная мембрана 1

 **Details

BPM smooth geomembrane is made from high grade Polyethylene raw material,adding

carbon black,antioxidant,anti-aging and UV-resistance component. It adopted the first class

automatic production equipment and three-layer pressing technology. All products are in accor-

dance with GRI and ASTM test standard.

**Feature

• Easy process and high output rates


• Excellent distribution of carbon black


• Consistent quality and low failure rate


• Excellent resistance and good waterproof ability


• Good welding

**Welding procedure

 1. Hot wedge welding process including: pressure adjustment,temperature setting,overlap checking,insert membrane into welding machine,starting motor,pressing and welding.

2. Prior to seaming,the seaming area is free of moisture,dust,dirt,sand or debris of any nature.

3. Before welding, test seam by one 0.9m×0.3m specimen and overlap not less than 10cm.After that,test the peel strength and shear strength.When approved,official welding can be performed according to the prior settings and mark the date,time and ambient temperature.

4. Seam line should be tidy and free of slide welding.

5. No wrinkle is allowed. When laying geomembrane,variations should be set aside according to temperature and property requirement.

6. After welding,test should be adopted to examine the welding quality.
